General description

Pentaerythritol is acrystalline , odour less white solid. The presence of neopentane core and four terminalhydroxyl groups makes it a versatile substrate for the synthesispolyfunctionalized compounds.

Application

Pentaerythritol can be used as a starting material to prepare four armed polyurethane prepolymers, which are applicable in the synthesis of UV cured polyurethane dispersions.

It can be used as an additive in the preparation of flame retardant polymers.

It can also be used as a precursor to synthesize polyethylene glycol/4,4′-diphenylmethane diisocyanate/pentaerythritol copolymer which is applicable as heat storage material.

Application of a novel sulfonate-based traceless multifunctional linker system using pentaerythritol as a tetrapodal soluble support was demonstrated using liquid-phase parallel and combinatorial preparation of biphenyl and terphenyl compounds. Nickel-catalyzed reactions of pentaerythritol tetrakis(arenesulfonate)s with arylmagnesium bromides generated the desired

The objective of this study is to develop a sensitive temperature-responsive material that would function near body temperature. To achieve this purpose, we compounded 2-branched and 4-branched poly(epsilon-caprolactone) macromonomers to modulate the transition temperatures of the resulting cross-linked materials. The
